PEDONIETER.

SPECIFICATION forming part of Letters Patent No. 770,644, dated September 20, 1904.

Application led April 30, 1904. Serial No. 205,814. (No model.)

To nl?. '1l/'7mm it party concern:

Be it known that l, EDMOND KUHN, a citi- Zen of the United States, residing at East Orange, Essex county, State of New Jersey, have invented new and useful Improvements in Pedometers, of which the following is a specification.

By means of this invention the length of steps can be plainly shown and correct adjustment can be readily obtained by a simple construction.

This invention is set forth in the following specification and claims and illustrated in the annexed drawings, in which- Figures l and 2 show opposite face views of a pedometer embodying this invention. Fig. 3 is a section along ai, Fig. l. Fig. 4 is a section along 1/ y, Fig. 2. Eig. 5 is a section along .e e, Fig. l.

In the drawings are shown frame-plates a a2. The pendulum or weighted arm is shown at and to its stad b2 is secured one end of the spring t. The other end of this spring is braced, as presently described. This spring tends to hold the pendulum to the stop CZ, and as under the influence of a step or other impulse the pendulum swings away from the stop the spring will return such pendulum. The pendulum is thus oscillated as the person carrying the instrument walks or causes movement. This spiral spring secured, as stated, to the pendulum-stal is also secured or braced against an arm c', pivoted at /c by means of a stud or the like. This stud may extend through the opposite side or plate or be secured to only one plate or between the plates, as no limitation of the invention resides in the various arrangements. This pivot f; is friction-tight, or does not move under the strain or tension of the spring. 1f, however, the pendulum for its proper swings requires either a stronger or weaker tension, the pivot 7;' or arm c' is turned or set to accomplish the desired object or regulation of the spring according to the direction of the turn. The pivot might, if desired, have a notch for engagement by a screw-driver or tool to aid in adjusting or setting.

The swing of the pendulum away from the stop CZ is limited by adjustment-screw e. The space between parts CZ or the degree of swing must of course be regulated according to the length of step if the pedometer is to correctly measure or indicate a walk or distance. The screw e is supported by stud c, (shown secured to a frame-plate.) The head of the screw has transverse holes, which offer convenient means for the insertion of a pin or the like to turn or set the screw. This screw head or bottom rests against an end of a lever f, fulerumed at f2, or rather a spring f3 by its tension holds the lever to the screw. This lever is shown with one of its arms at one side of a frame-plate andthe other arm at the other side; but of course this arrangement could be changed or modified without departing from the invention.

The screw e as it is turned or adjusted will cause the leverfl to swing, and as said lever moves or sweepsalong a scale g the degree of setting or adjusting of the screw is observed. In case the lever or an arm thereof lies under a frame-plate, as in the particular example shown, the plate has to be cut or provided with a sight or opening to allow the end of the lever which forms the index or indicator part to be seen and its position or movement along the scale or slot to be noted. As seen even on a slight movement of the screw the lever following the screw and arranged as shown will show by its end or by its longer arm the movement of the screw in an enlarged degree.

The lever shown might be said to be a lever of the first class; but of course by a manifest transposition of parts or shift of the fulcrum this index or hand might be another leveras, for example, of the third class and actuated by the screw in any suitable manner.

Familiar parts of the pedometersuch as the pawl, spring, and ratchet connection from the pendulum to the train of gears and the like -need no explanation.

That l claim as my invention, and desire to secure by Letters Patent, is*

l. A pedometer provided with a pendulum, a regulator or adjustment-screw for determining the swing of the pendulum, andan index or hand engaged by the screw to be set thereby.

2. A pedometer1 having a pendulum and an index, Combined with an adjustment-screw one end of which serves to limit the play or swing of the pendulum and the other end of which serves to set the index.

3. A pedometer havinga pendulum and an index, combined with an adjustment-screw one end of which serves to limit the play or swing of the pendulum and the other end of which serves to set the index, and a spring for holding the index to the screw.

4. A pedometer Comprising' a pendulum, an

adjustment-screw for the pendulum, and an index or indicator lever fulerumed to a plate or part of the pedometer, said screw being made to aetuate the lever so that the latter will malre a sweep or swing' as the screw is set or adjusted.

1n testimony whereotl I have hereunto set my hand in the presence of two subscribing witnesses.

EDMOND KUHN.
